Cantera Negra is handcrafted in small-batch quantities from late-harvest Blue Weber Agaves. We do not believe in cutting corners, and permit only time-honored, traditional methods and the studied art of blending to guide our approach to production. Unlike so many others, we do not ever add any sugars or colorings to our tequilas. Because of our proven approach, the outstanding quality of our all-natural product speaks for itself.
